UNITED STATES CHARLES J. KOEPKE, OF CHICAGO, IL LINOIS.

FOUNTAIN TOOTHBRUSH.

Application filed September 21, 1921. Serial No 502,088.

To all whom it may camera:

Be it known that I, CHARLES J. KonrKn, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented new and useful Improvements in Fountain Toothbrushes, of which the following is a specification.

This invention relates to tooth brushes which are provided with a hollow handle adapted to seat a compressible tube or the like containing a tooth paste or cream which is fed to the bristle tufts of the brush when the brush is about to be used. 7

The invention has for its object to provide a structure of the kind stated which is adapted for the ordinary compressible tubes in which tooth pastes and creams are put up and sold.

The invention also has for its object to provide a simple. structure, and one which is compact and easy to'manipulate for use.

With these and other objects in view, as-

will appear hereinafter, the'invention consists in a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is bad to the accompanying drawing, in which Figure 1 is an elevation of the device, partly in section; Fig. 2 is an enlarged sectional detail, and Fig. 3 is an enlarged crosssection on the line 33 of Fig. 1.

Referring specifically to the drawing, the

handle of the brush is composed of inner and outer tubular members 5 and G which are closed at their rear ends.

member has a reduced portion or neck 5 at its forward endwhich is internally screw threaded to receive a threaded rear-extension 7 of the brush head 8 carrying the bristle tufts 9. This construction provides a rigid but detachable connection between the handle and the brush head.

In the member 5 is adapted to seat the compressible tooth-paste or cream tube 10,

the same having an externally threaded outlet neck or nipple 10 as usual. On this neck is screwed the base 11 of a nozzle tube 12 which latter extends forwardly and passes through a central longitudinal bore in the part 7 and is then continued along'the under side of the brush head 8 to discharge into the mass of bristle tufts 9. i

The inner The forward end of the member 5 is threaded externally so that the member 6 may be screwed thereonto, and said members are provided with side openings, the opening of member 5being shown at 13 and the opening of member 6 at 13. \Vhen the member 6 is rotated sufliciently to bring its side opening into registering position with respect to the sideopening of themember 5, the side of the tube 10 is exposed, and hence said tube may now be compressed to eject its contents through the nozzle 12 into the mass of bristle tufts 9. When the brush is not in use, the member 6 may be rotated to take its side opening out of registering position with respect to the side opening of the member 5, so that the tube 10 is now completely closed in to prevent it from being accidentally squeezed to eject its contents.

The brush head is adapted to be enclosed in a screw cap 14 detachably fittedto the forward end of the member 5. This cap also carries'a plug or closure 15 for the nozzle 12, said closure being a rod. end of cap 14 carries a slidable finger piece 16 which is normally projected outwardly by a spring 17 and to the inner end of this,

finger piece is attached the closure rod 15. Then the brush is about to be used the. rod

The forward, j

15 may be reciprocated in the nozzle 12 by pressing inwardly on the finger piece 16 and then releasing the same. This action clears the nozzle 12 of any caked paste or cream.

The structure hereinbefore described prorides a simple and eflicient fountain brush, v

and one to which any ordinary tooth paste or cream tube of the compressible type may be applied.

I claim:

A fountaintooth brush comprising a hollow handle and a bristle head, a dentifrice CHARLES J. KOEPKE.
